Question Regarding Right Click to Cancel operation vs. Perform in place

Well, I broke Blender. Now it’s time for me to walk away in shame.

Actually, I probably did something very noobish that someone here will get a good laugh over.

I’ve swapped my mouse clicks so that left selects. Normally if I select an object and Shift+D, then right click I duplicate the object in place. Similar behavior with Ctrl+R, etc.

Somehow I’ve changed the behavior so that right click cancels the operation. The last thing I did before this happened was install the pie menu add on, but I’m not sure what setting I accidentally clicked to change the right click behavior.

Could someone please explain what I’ve done so I can change it back, and hopefully learn some amazing new workflow tricks in the process?

Thanks!
